Abstract
A method for operating a hybrid vehicle which comprises at least one internal combustion engine with a fuel tank and a filter, and an additional motor for driving the vehicle. The filter is designed to receive fuel vapors from the fuel tank in a filtering mode and to discharge the fuel vapors to the internal combustion engine in a flushing mode. In the method, a current operating point of the internal combustion engine is detected and the flushing mode of the filter is activated according to the current operating point and an operating time of the vehicle.
